UniProtKB description:  Involved in nicotine degradation (PubMed:24204321, PubMed:26237398, PubMed:29812904, PubMed:33432238). Catalyzes the conversion of nicotine to N-methylmyosmine (PubMed:24204321, PubMed:29812904, PubMed:33432238, PubMed:33464876). N-methylmyosmine undergoes spontaneous hydrolysis to form pseudooxynicotine (PN) (PubMed:24204321). S-nicotine is the optimal substrate (PubMed:29812904). Has lower activity with some nicotine analogs, but shows no activity towards neurotransmitters, including serotonin, dopamine, and norepinephrine, nicotine metabolites and common neuroactive drugs (PubMed:29812904). The enzyme is stereospecific with poor activity with (R)-nicotine as the substrate (PubMed:29812904). The c-type cytochrome protein CycN is the physiological electron acceptor (PubMed:33432238). O(2) is a poor electron acceptor (PubMed:33432238, PubMed:33464876).
